# WIA-ENE-005 PHASE 1: Foundation

## Overview
Phase 1 establishes the foundational elements of the WIA-ENE-005 Solar Energy Standard, including core data models, basic monitoring capabilities, and essential safety requirements.

## Core Data Model

### System Profile
```json
{
  "siteId": "SITE-001",
  "name": "Residential Solar Installation",
  "location": {
    "latitude": 37.7749,
    "longitude": -122.4194,
    "altitude": 16,
    "timezone": "America/Los_Angeles"
  },
  "installedCapacity": 6000,
  "commissionDate": "2024-03-15",
  "standard": "WIA-ENE-005",
  "complianceLevel": 1
}
```

### Data Points
- **Production Metrics**: Current power, daily energy, cumulative energy
- **Environmental Data**: Irradiance, temperature, wind speed
- **System Status**: Operational state, fault codes, availability
- **Performance Indicators**: Efficiency, performance ratio, capacity factor

## Minimum Monitoring Requirements

### Level 1 Compliance
- System-level power monitoring (1-minute intervals)
- Daily energy production logging
- Basic fault detection and reporting
- Environmental conditions (optional but recommended)

### Data Retention
- Real-time data: 7 days minimum
- Daily summaries: System lifetime
- Fault logs: 1 year minimum

## Safety Requirements

### Electrical Safety
- Ground fault protection
- Arc fault detection (for systems >240V DC)
- Rapid shutdown compliance (NEC 690.12)
- Overcurrent protection
- Disconnect devices

### Physical Security
- Equipment labeling and warnings
- Access control for electrical enclosures
- Proper grounding and bonding

## Communication Protocols

### Required (Level 1)
- **Modbus RTU/TCP**: Basic inverter communication
- **HTTP/HTTPS**: Data upload to monitoring platforms

### Data Format
```json
{
  "timestamp": "2025-12-25T10:30:00Z",
  "systemId": "SYS-001",
  "power": 4850,
  "energyToday": 28.4,
  "status": "operational",
  "standard": "WIA-ENE-005",
  "version": "1.0"
}
```

## Implementation Checklist

- [ ] Define system profile with all required fields
- [ ] Configure monitoring for system-level metrics
- [ ] Implement data retention policies
- [ ] Install and test safety systems
- [ ] Verify communication protocols
- [ ] Document system configuration
- [ ] Conduct commissioning tests

## 弘益人間 (Benefit All Humanity)
Phase 1 ensures that even basic solar installations provide transparent, safe, and standardized operation—making solar energy accessible and reliable for all.
